A Good Day To Die Hard
The hook of this film, if you can even call it that, is the fractured relationship between our hero and the son that hasn't been mentioned since 1988. Die Hard and Die Hard 2 used his crumbling, then repaired marriage to give McClane some motivation for his actions aside from saving the day and obviously the powers at be thought it was a great idea to introduce John Jr./Jack (Jai Courtney, the pretty meathead from Jack Reacher) after his daughter Lucy (Mary Elizabeth Winstead wearing ugly as hell chinos) showed up in 4.0, but since everything they say to each other is forced, disingenuous and stripped of any wit or interest, it's up to the action to carry the film.
There are no decent supporting characters, the villain is so paper-thin that they have to make him tap dance and eat carrots to give him a personality, and apart from a Frank Sinatra-loving cabbie, all the humour and memorable lines that contributed to making Die Hard so great is gone. Most of the time John McClane wanders around wondering how he got himself mixed up in trouble again when he's supposed to be on vacation while the audience wonders what the point of all this is.
